胚层

Results demonstrated that the level of ROS was greater in embryo than in aleurone layer, and only very little ROS could be detected in starch. Furthermore, the ROS produced in embryo were mainly localized inside cells but not on cell membrane.

结果表明，胚细胞产生的活性氧最多，糊粉层细胞次之，淀粉细胞几乎不产生活性氧；而且，胚细胞产生的活性氧主要定位在细胞内，细胞膜上不产生。

Aleurone layer The outermost proteinrich layer of the endosperm of grass fruits (e. g. cereal grains).

糊粉层：在谷类种子胚乳最外面的一层或几层细胞，含有大量的糊粉粒。

The rearrangement of the blastula into a three-dimensional organism with inner middle and outer layers occurs during gastrulation.

在原肠胚形成过程中，囊胚重新排列，形成包括内层，中层，外层的三围组织。

Germ potential is established after conception in a totipotent zygote and retained subsequently during development in blastomers of morula , cells form the inner cell mass of blastocyst , epiblast and population of primordial germ cells .

种子潜能的确定是全能的受精卵形成之后，并且随后在桑葚胚，胚泡内层细胞，外胚层和原生殖细胞的发育过程中保留。

The ovule of development is the one nucellus that make a group at first organization, because basilar segmentation is rapidder and form or two bags by the layer, bead by , other nucellus the organization laps inside and next alveolus stays in one aspect of the matter, bead aperture .

发育的胚珠最初是一整团珠心组织，由于基部的细胞分裂较快而形成一层或两层包被层—珠被，将其他珠心组织包裹在内并在一端留下一个小孔—珠孔。

It is a L-good extention , a invariant of weak homeo-morphisms, and it is hereditary,producible.

这种层完全T_2分离性具有弱同胚不变性，遗传性，在积运算下保持等性质，且弱诱导的层T_1的层正则L-拓扑空间是层完全T_2的。

Seeds ellipsoid to pyriform, dull to ± shiny; seed coat with thick inner layer of dense black sclerenchyma surrounded by outer layer of compact parenchymatous tissue; endosperm copious; embryo straight or nearly so; cotyledons ovate to elliptic, flattened; hypocotyl superior.

种子椭圆形到梨形，黯淡到发亮；种皮具厚的紧密黑色的厚壁组织内层，被紧密的薄壁组织外层所包裹；胚乳丰富；胚直立或近直立；子叶卵形到椭圆形，扁平；下胚轴上位。

Seeds remaining attached in dehisced fruit; seed coat with thick inner layer of dense black sclerenchyma and spongy outer layer bounded externally by a shiny black pellicle; endosperm copious; embryo straight or slightly curved; cotyledons elliptic, flattened; hypocotyl superior.

种子附存于开裂的果中；种皮具厚的内层深黑色厚壁组织和海绵状的外层，其外部边界具发亮的黑色表膜。胚乳丰富；胚直或稍弯曲；子叶椭圆形，扁平；下胚轴上位。

The simple pigment epithelial cell layer, the optic ventricle, the primitive neuroblastic layer and the peripheral fibrous layer were observed. The number of both the retinal layer and cellular layer increases in the 35 day old Giant panda.

发现胚后64小时龄大熊猫视网膜的分化程度很低，色素层已形成，但视泡腔明显；神经层由外面数层长梭形、内面数层圆形细胞核及无核的纤维层构成。35天龄大熊猫视网膜细胞层次增多。

The depth of tectal layerⅠand the morphological characteristics of tectal cells in layerⅠwas investigated using Nissle staining, Golgi staining, and postmortem labeled with DiImethod. Most ofⅠcells appeared shuttle, others showed round, oval, pyramidal, triangular,and polygonal etc. The lateral region of layerⅠwas thicker than the ventral and the dorsalregions.

本研究使用Golgi-Cox法，灌流固定后尼氏体染色、羰花青荧光染料DiI(1，1′-dioctadecyl-3，3，3′，3′-tetramethylindocarbo-cyanine perchlorate)逆向神经标记技术，对雏鸡视顶盖Ⅰ层的厚度和该层的细胞形态、大小进行了观察研究和数理统计，并对不同日龄鸡胚的Ⅰ层厚度进行了数理统计及分析研究。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
